    Question C++ program jumps for noobie

    I am a noobie c++ programmer and have a Question on how to
    complete this program

    I want to be able to input a or v and then be able to jump to the area to input and calculate my result and display
    I tried goto(i know dont laugh)
    and tried bool but it didnt work

    someone help me


    #include<iostream>


    int main()

    {

    int area, volume, height, width, length;

    std::cout<<"\nDo you wish to calculate Area or volume?(A/V)";

    char av;

    std::cin>>av;


    { //input and calculate area
    std::cout<<"\ninput width:";
    std::cin>>width;
    std::cout<<"\ninput length:";
    std::cin>>length;
    area=length*width;
    std::cout<<"area is:";
    std::cout<<area;
    }

    { //input and calculate volume
    std::cout<<"\ninput width:";
    std::cin>>width;
    std::cout<<"\ninput height:";
    std::cin>>height;
    std::cout<<"\ninput length:";
    std::cin>>length;
    volume=height*width*length;
    std::cout<<"\nvolume is:";
    std::cout<<volume;
    }
    return 0;

    }

    first use code tags.

    as for the problem, just use if statements.
    Code:
    if(av == 'a') {
       //area calculations
    } else {
       //volume calculations
    }
    and for goto, not recommended. it tends to be sloppy code.

    Try using IF statements:
    Code:
    if (av == 'a')
    {
         // Calculate Area....
    }
    
    else if (av == 'v')
    {
         // Calculate Volume....
    }
